Abstract (en)

[origin: EP1433541A1] Coil sensors (18) forming components of LC oscillators are located below a horizontal flow of material, to measure induced eddy currents. Additionally, opto-electronics (14) locate each particle of the bulk material, in order to determine where it shall be blasted from the stream. An Independent claim is included for the corresponding method of sorting metallic fractions from a flow of bulk materials. Preferred Features: The coils are operable at 100 kHz. Each is located in a pot, the concentrated magnetic field lines emerging from the open top face. Each pot is integral with a central, perpendicular ferrite core. The coils are arranged in parallel, equidistant, semi-staggered rows. The coils of each row may together be set at various distances from the flow. Signals from a sensor coil are sent to a demodulator and trigger circuit, for signal level evaluation. The vertical coil spacing can be varied w.r.t the horizontal conveyor. To determine the class of a particle, the measured electromagnetic characteristics are correlated with optically-measured data. Electromagnetic particle characteristics measured, are correlated with high resolution color data, as the particle falls.
